I am a contractor by trade and understand the costs/processes to build, but I am lacking in how to determine a proper sale price with little data. 

I want to open up the HELOC to have as our emergency fund so I can deploy some of the cash we have saved up right now.

Arranging schedule of various trades and balancing the good ones with the ones that are available.Permitting and inspection issues (should be a non-issue, but last house we had a new inspector that seemed like he had something to prove and nitpicked what I view as non-issues).Market swings impacting ARVs, or in the current market: are we going into a recession before the house can be completed?

There is a high demand for high paying trade work, often with scholarships and two year degrees.

(unless you day job is in the trades)

The whole term of wholesaling originates on the fact you don't close on a deal with your own money you just sell a contract like options trading.

We will also finish up some renovation on our owner occupied house and pull a HELOC for an emergency fund and possible rental purchase fund.What are you looking to do, @Kristie Laufer? 

I am not a mortgage person but the "bait and switch" in the business is called "re-trading a loan".My contacts get this a lot.Some company touts they can do a rate for xx with little to no down.They collect a bunch of fees and then right about when closing they say something happened and have to move to a new higher rate.Don't believe the HYPE!!

We keep a window unit in reserve to install in emergency situations.

Since he is selling in the US, this can be any real property in the US that going to be held for business, investment, or trade use.
